Both are HSV-1, and they look different because the tissue is different. On the lip: a cluster of blisters that crust over and heal in 8–12 days. Inside the mouth: blisters break down within hours into shallow ulcers, so you often never see the blister stage at all — which is precisely why intraoral herpes gets mistaken for canker sores.
Have a sore right now? Swab it today while it is fresh — lesion PCR is the most reliable herpes test there is, and it loses sensitivity as the sore crusts over.

Three things people confuse
| Cold sore (lip) | Intraoral herpes | Canker sore | |
|---|---|---|---|
| Location | Lip border | Gums, hard palate | Inner cheek, under tongue |
| Blister phase | Visible, days | Brief — often missed | None |
| Grouping | Cluster | Cluster | Usually single |
| Contagious | Yes | Yes | No |
| Test | Lesion PCR — swab it | No test needed | |
Do not accept an HSV IgM blood test. CDC does not recommend it — it generates false positives and unnecessary panic. If there is a sore, swab the sore. See lesion PCR vs. antibody testing.
We name drugs, never doses. Antiviral therapy for HSV follows CDC guidance; what you take is decided by a licensed physician who has examined you.
The single most useful thing on this page. If you have a sore right now, get it swabbed today — lesion PCR identifies HSV and types it (HSV-1 vs HSV-2). Sensitivity falls as the sore dries, so the best day to test is the day it appears. Sample by 1:00 PM → result at 4:30 PM → licensed partner-network physician 4:30–6:00 PM if treatment is clinically appropriate. Same day. Walk in, no appointment, no insurance. Text (713) 832-8892.
FAQ
- Why does it hurt so much to eat?
- Ulcerated mucosa is raw. A physician can advise on symptomatic management as well as antiviral therapy.
- How long until it heals?
- Typically 8–12 days. Persistent or worsening lesions past two weeks need a clinician.
- Can adults get a first episode?
- Yes, and it can be severe. Come in.
- How fast can I know?
- Same day — swab by 1:00 PM, result at 4:30 PM.
The sore will crust over in a few days — and the test gets less reliable as it does.
